lo a/ZZ whom it may concern:

Be it known that I, D D MILLER, a citizen of the United States, residing at Wooster, in the county of Wayne and State of Ohio, have invented new and useful Improvements in Hay-Carriers, of which the following is a specification.

This invention relates to hay-carriers; and one of the principal objects of the same is to provide simple, reliable, and eficient means for locking the lifting-head or pulley to the carrier-frame.

Another object is to provide simple means for locking the lifting-head within the carrierframe without the use of springs.

Another object is to provide simple and reliable locking mechanism for the lifting-head or pulley which will permit said lifting-head or pulley to be swung to a horizontal position within the throat of the carrier-frame in order to permit the load to drag over obstacles and to also enable the load to be carried close to the comb of the roof of the haymow.

These and other objects are attained by means of the construction illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of an openthroat hay-carrier made in accordance with my invention, the lifting-head being shown suspended from the carrier-frame by means of the operating-rope. Fig. 2 is a side view showing the lifting-head or pulley connected tothe carrier-frame and swung to a horizontal position. Fig. 3 is a central longitudinal section of the carrier-frame. Fig. 4 is a perspective view of one of the locking-pawls for the lifting-head. Fig. 5 is a perspective view of the gravity-latch for holding the pawls in position to lock the lifting-head to the carrior-frame.

Referring to the drawings for a more particular description of my invention, the numeral 1 designates the angle-iron track upon which the carrier-frame is supported, said angle-iron track consisting of a pair of angleirons secured together and spaced apart by means of rivets passing through spacingsleeves. The carrier-frame consists of the casting 2, having bearings for the four wheels 3, upon which the carrier is supported upon the track 1. Thelower portion or the throat of the carrier consists of the circular upper portion 4, supported upon and adapted to revolve within a similar annular support 5 upon the upper portion of the frame. The throat portion consists of two halves or sections secured together by means of the bolts 6, each section or member consisting of a iiaring throat portion 7, having a guideway 8 for the hub of the lifting-head or pulley. A pulley 9 is journaled between the two throat members, over which pulley the operating rope passes, said rope passing under the pulley 1() uponthe lifting-head 11 and up through an opening 12, provided with a knot-socket 13. The locking-pawls 14 are provided with a projecting lug 15, a curved portion 16, and a recess 17, which forms a continuation of the guideways or grooves 8 in the throat when in one position, said pawls being pivoted upon studs 18, projecting inward from the frame of the throat. A gravity-latch for locking the pawls in position to support the lifting-head consists of a casting having integral pintles 19, which are journaled in openings in the frame of the throat at opposite sides of said latch, and the opposite end of said latch is adapted to drop by gravity in position to hold the lug 15 of each pawl in position to form a complete bearing for the opposite hubs of the lifting-head. When the latch is lifted, the pawls may be swung to a position so that the recess therein will register with the guideways in the throat and permit the hubs on the lifting-head to pass inward or outward, as will be understood. The gravity-latch is provided with a curved surface 20, which conforms to the curvature of the lug 15 and is provided with a projecting lug 21.

The operation of my invention will be understood from the foregoing and may be described as follows: The lifting-head is lifted into position to be connected with the carrier'- frame by means of the operating-rope 22, the hubs Q3 of the lifting-head passing into the guideways at the sides of the throat and into the recess in the locking-pawls. When the load has been carried to its destination, the projection 24 on the gravity-latch comes into contact'with the trip-block 25, and this raises the lug 21 from behind the lug l5, as shown in dotted lines in Fig. 3. The weight of the load will then move the locking-pawls 14 to a position to permit the load to be lowered and discharged. The pawls 14 remain in the position shown in dotted lines in Fig. 3 until the pulley 1() is raised into the carrier. Then the hubs 23 pass into the recesses 1T, and when the rope 22 is pulled the hubs ride upon the ianges 23X, where they are supported until the projection 24 is again brought into contact with the trip-block to unlock the latch.

IIO

From the foregoing it will be seen that the carrier-head may be suspended from the frame and pivoted thereto in a manner to swing horizontally when brought into contact with obstacles and when it is desired to unload at a point near the roof of the haymow.

My device is operated without the use of springs and is composed of comparatively few parts, which are not liable to get out of order and which are strong, durable, and reliable in operation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a hay-carrier an open throat provided with a guideway for the hubs of the liftinghead in combination with a pair of pivoted pawls having recesses conforming to the guideways, a pivoted gravity-latch for locking said pawls in position to prevent the hubs of the lifting-head from disconnection with the carrier-frame and means upon the track for tripping said 'pawls and releasing the lifting-head', substantially as described.

2. Ahay-carrier comprisingaframe, wheels journaled therein and mounted to run upon an angle-iron track, a carrier-throat swiveled to said frame, a guideway in said throat, pawls pivoted at the upper end of said guideway and provided with recesses forming a continuation thereof, supporting-flanges upon said frame, a lug upon each of said pawls, a gravity-latch adapted to drop into contact with said lugs, a carrier-head comprising a pulley mounted in a frame having hubs, and means for disconnecting the gravity -latch from the pawls, substantially as described.

3. In a hay-carrier an open throat provided with guideways, pawls having recesses forming continuations of the guideways, a iiange on opposite sides of the frame, a carrier-head provided with hubs adapted to be carried into the recess in the pawls and means for shifting the pawls to carry the hubs to a position to be supported upon the lianges, means for locking the pawls in this position and means for unlocking the pawls, substantially as described.

4. In a hay-carrier, a lifting-head comprising a frame having hubs, a pulley mounted in said frame, a carrier therefor having guideways for said hubs, pawls mounted in line with the guideways and having recesses which form continuations thereof, locking-lugs upon said pawls, a gravity-latch for said pawls and means for lifting said gravity-latch out of contact with the pawls at the point of discharge of the load, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
